Guys. Guys. Guys... Guys ... ... ......... It's good. Seriously though. Do your best to avoid spoilers. Get the FLUP off reddit, don't look at ANY youtube comment sections, stay off Facebook's front page, etc.
Stylistically it's heavily leaning to the OT side, not the prequels. I think it has something for everyone. It already irreversibly changed Star Wars for me. Watching older Lightsaber battles is painful, because i'm missing them giving off light like in TFA
It'd be best to watch the OT first. Otherwise they might keep leaning over and asking "who's that? what's that?" and the returning cast won't have the same impact. It's not perfect. But like, what movie is? I wouldn't give it anything below 8/10.
Saw it. Enjoyed it immensely. Will not talk about it till Monday and people have had a reasonable chance to see it.
